Train window Observation

I noted a little earlier that different images of the same object produce the illusion of relief when in rapid alteration they perceptibly fuse. Does this happen only when we see moving images and stand still ourselves? Alternatively, will it also take place when the images are standing still but we are moving? Yes, we get the same illusion, as was only to be expected. Most likely, many have noticed that movies shot from an express train spring into unusually clear relief, just as good as in the stereoscope. If we pay, heed to our visual perceptions when riding in a fast train or car we shall see this ourselves. Landscapes thus observed spring into clear relief with the foreground distinctly separate from the background. The stereoscopic radius of our eyes increases appreciably to far beyond the 450 meter limit of binocular vision for stationary eyes. This explains the pleasant impression we derive from a landscape when observing it from the window of an express train Remote objects recede and we distinctly see the vastness of the scenic panorama unfolding before us. When we ride through a forest, we stereoscopically perceive every tree, branch, and leaf; they do not blend into one flat picture as they would to a stationary observer. On a mountain road, fast driving again produces the same effect. We seem to sense tangibly the dimensions of the hills and valleys.
